on the particle as a function of x.
b) For what values of x is the force equal to zero?
c) Plot U(x) versus x and
F
x
versus x and indicate the points of stable and unstable equilibrium.
Potential Energy and Force:
When an object has potential energy, either gravitational, elastic or some other type, it has a force acting on it. The force on the object is the negative derivative of the potential energy function. The graph of this function shows locations of stable and unstable equilibrium.

(b) The force is zero at x = -0.453 m and 1.29 m.
(c) There are two positions of equilibrium,.
Answer:
x^2-5x=0 if it is in equilibrium position
x(x-5)=0
x=0 or X=5
